Diazotization Reaction
In diazotization Reaction, The aniline is treated with nitrous acid ( a mixture of sodium nitrite and hydrochloric acid) at temperature 00 to 50 Celsius ( 273 K to 278 K ) to produce diazonium chloride.
Nitrous acid is produce in the reaction mixture by treating NaNO2 with HCl
NaNO2 + HCl —> HNO2 + NaCl
Diazonium salt is highly unstable and can explode at little higher temperature therefore it is prepared at lower temperature (00 to 50 Celsius).
Diazonium salt can not be separated and product mixture is used for further reaction because diazonium salt is highly unstable and explode on distillation (on heating).
Diazonium salt is very much important in organic synthesis as for preparation of large number of organic compounds, it is precursor (Reactant).

Aldol Condensation Reaction
Hoffmann Bromamide Degradation Reaction
1.In this reaction amide is treated with bromine in presence of sodium hydroxide to prepare primary amine.
2.This method is used to prepare only primary amine not secondary and tertiary amine.
3.In this reaction product has one carbon less than reactant that’s why it is called degradation reaction.
